To all whom it may concern: H

Be it known that JAC KSbN M. Ron, a citizen of the United States,residing at Sunnyside, in. the county of Yakima and State of Washington,'have invented new and useful Improvements in Lock-Nuts, of which thefollowing is a specification. The general object of this invention isthe provision of a locking nut particularly adapted for use inconnection with axle spindles, said nuts being constructed in-a novelmanner and provided with means for engaging the free end of 'a spindlewhereby the rotation of'said nut on said spindle 'will be prevented,thus insuring against acci dental displacement thereof.

In carrying out the objects of the inven tion generally stated above, itwill be understood, of course, that the essential features thereof aresusceptible to changes,in details and structural arrangements, preferredand practical embodiments being shown in the accompanying drawing,wherein Figure 1 is a side elevation of a preferred form of theinvention. Fig. 2 is a vertical longitudinal sectional view thereof..Fig. 3 is an end elevation. Fig. 4 is a vertical longitudinal sectionalview of a further em bodiment of the invention. Fig. 5' is an endelevation of the modified form.

Referring to the accompanying drawing and more particularly to F l to 3inclusive, 6 indicates the spindle of the ordinary well' knownconstruction and having its outer end provided with the serrations 7 fora purpose which will be presently described. The nut 8 is provided withthe threaded opening 9 which is adapted to engage the threads of thespindle, said nut being'provided in its outer end with alined slots 10.A pivot pin 11 is mounted in said nut adjacent one. edge thereof andextends at, riglit angles to the alined slots 10. Mounted ,in one of theslots 10 and cbiled about the pivot pin 11 is a locking s rin 12 whichis formed from a single leng&

0 suitable metal, one end of said spring being adapted to engagetheadjacent outersurrace of said nut whereby the free end of said springwhich extends across the nu t i's' :tensioned and caused to normally beseated in the opposite slot 10 so that said spring will engagethe-serrations formed in the end of the spindle 6. When in this positionthe nut will be prevented from rotation upon the spindle whereby the.possibility of displacement of the same will be obviated. The freeextremity of the spring 12 is bent upon itself to provide a finger grip13 whereby saidspring, may be drawn from engagement with the serrations7 and thus permit the ready removal of the nut.

The embodiment shown in Figs. 4 and 5 of the drawing comprisesa nut 14having a threaded opening 15 extending longitudinally thereof, said nutbeing provided with a closed outer end 16 having an elongated ing spring18, one end of which is coiled about the pivot pin 19 which extends atright angles to the slot 17. The locking spring 18 is providedintermediate its ends with a lateral extension 20 which projects beyondthe outer end 16 of 'the nut thus affording a finger grip whereby the.free end 21 of said spring may be withdrawn from engagement with theserrations formed on the end of the spindle thus ermitting the freeremoval-of the nut there rorn.

From the foregoing description taken in connection with the drawing itwill be seen. that the invention contemplates providing a nut lockwhichis simple in construction thus reducing the cost of manufacture ofthe same to a minimum and which is effective in a in presence of twowitnesses.
